I have a Sony Bravia television that is about 2 and a half years old. For about a year, each time I would turn the television on the picture would be split down the middle with one half of the picture "brighter" than the other half. After ten or so minutes it would equalize and the entire picture would be consistent. Now, after about ten minutes the picture becomes extremely bright and some colors (especially that of human skin) tends to shine and reflect light. The picture also appears to be more blurry than before, almost bleeding colors. Any ideas?
